And there is every point not doing so.

I've just realised that I haven't made my position clear - I think that
if it is something we have measured, it should be in metric units. If it
is a rule we have recorded, like a legal limit, then it should be kept
in the units as supplied, because 50km/h is not the same as 30mph.

In the case of canal heights and widths, I'm not sure what are rules
from the canal authorities, and should therefore be kept in the units in
which they originate, and what are things that Richard and Co are
estimating or measuring with their GPSs and other tools.
